Migrate all posts?

Hello, I have a blog for my company: https://blog.controlgroup.es/ And now we have a new website for the same company: https://www.controlgroup.es Well, I bought your plugin to display my blog posts on my website. In the blog I have more than 200 Posts and on the web I have configured it to show 100 Posts, but it only shows 8 (I attach screenshot 1 and 2). Why doesn't it show all the Posts? And another question: I see that in addition to displaying the Posts, the plugin makes a copy of the original Post on my website. This interests me. But it only makes a copy of the Post excerpt, not the entire Post. Is there a way for me to copy the entire Post? I say this because that way, I could make a copy of all the Blog Posts to the web and permanently delete the blog. Thank you
